Established by Nathaniel Jarvis Wyeth in 1834 along the Snake River, Fort Hall first served as a fur trading post. The British flag flew over Fort Hall briefly when it was purchased by an English company, until a treaty placed it and the rest of the Oregon Country in United States territory. Early emigrants on the Oregon Trail usually abandoned their wagons at the fort and continued on foot with their animals. But in 1843, Dr. Marcus Whitman, who had established a mission near Walla Walla, Washington, led a wagon train westward from the fort. From then on, migrations along the trail increased as the pioneers could now travel all the way to Oregon with their wagons and possessions.
